Application filed May 15, 1917. Serial No. 168,754.

To all whom it may concern:

Be it known that I, ARCHIBALD W. BARN- .BY, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented new of which the following is a specification.

This invention relates to tobacco, and more especially to pipes or smoking tubes; and the primary object of the same is to mix with the smoke steam which is generated in a space adjacent the bowl by the heat of the burning tobacco in the latter.

Another object is to provide a jacket surrounding the bowl so as to prevent the latter from burning the user. a

Another object is to provide means for preventing the water in the jacket from getting into the bowl when the pipe or smoking tube is inclined.

Another object is to provide a pipe of this kind with a nicotin chamber and means for cleaning it, without interfering with the general object of the invention.

These and other objects are'carried out in the manner hereinafter more fully described and claimed, and as shown in the vdrawlngs where1n:

Figure 1 is a sectionalview through one form of pipe embodying my invention,

Fig. 2 is a sectional view through another form,

Fig. 3 a sectional view through a smoking tube.

Fig. 4 is a sectional view through another form of pipe.

In all these views the letter M designates the mouthpiece-whose bore communicates with the receptacle R for the tobacco. If the device be a pipe, there is a stem S connected with the lower end of the bowl'B. If the device be a smoking tube, the tube itself lettered T in Fig. 3, has its bore communicating with that of the mouthpiece M and enlarged at its outer end to produce the receptacle R. I would state here that I do not wish to be limited in any respect as to the size,.shape, configuration, or material of the smoking device whether it be a pipe or a tube, excepting as the same must be adapted to the invention. I have shown in Fig. 1 means for producing a nicotin chamber accessible through an opening which is closed temporarily by a plug, but

in Fig. 2 the same chamber is closed permanently. These also are details which may be left to the manufacturer.

Coming now to the present invention, and

referring first to Fig. 1 wherein is shown a pipe whose bowlhas its axis substantially at right angles to the length of the stem S so that'ordinarily the bowl would stand upright when in use or when laid on a table (as distinguished from the type of pipe shown in Fig. 2 and described below), the tobacco receptacle R which is the equivalent of the chamber within the ordinary bowl may be open at its top as at 1 and in any event must communicate at its lower end with the bore 2 of the stem S. In the illustration the communication is by means of an outlet 3 from the bowl proper into a nicotin chamber 4 in the base of the structure, and the inner end of the stem enters this chamber through the opening 5 and projects from the bowl at substantially right angles as shown. The bottom of this chamber may have a cleaning or outlet opening 6 ordinarily closed by a plug 7, and when this plug is removed access to the chamber 4 is permitted so that nicotin and other accumulations therein may be cleaned or washed out. The essential feature, however, consists in'providing a jacket entirely surrounding that portion of the bowl B which contains the receptacle B. This jacket is broadly designated by the numeral 10 which also refers to the space therein.

t is formed by making the walls of the bowl double so that the outer wall is spaced somewhat from the inner wall to produce the annular jacket 10 as shown. On what might be called the inner side of the bowl, that is, next the user, the inner wall 12 at its lower portion is thickened as at 13, and bored upward through this thickened portion of the wall is a fine duct 14 whose lower end communicates with the chamber 4 and whose upper end communicates with the interior of the jacket 10 at a point about half-way of the height of the latter. A filling opening 15 is provided at an appropriate point in the outer wall 11, and is closed by a plug 16.

The construction illustrated in Fig. 2 is much the same, and the exceptions may be explained as follows: Herein is shown what might be called a dropped stem S, that is to say, it is supposed to hang obliquely from the mouthpiece M to the bowl B so that when in use and with the axis of the bowl upright, the stem stands oblique to such axis or at an acute angle thereto. I have made use of this view to show that the nicotin chamber 4 might be closed by a permanent plug 27, sealing an opening in the bottom located like the opening 6. In both cases these openings are directly in line with the fine duct 14 so that the latter may be bored by inserting a tool through the opening before the plug is appl ed. The jacket 10 is here somewhat amplified, and especially is it enlarged at the inner s1de of the bowl as at 20s0 much so, in fact, that the filling opening and plug 16' are preferably'placed quite near the opening 5 for the stem.

In either case I propose to fill the jacket a little less than'half full. of water or suitable and appropriate liquid, and therefore when the bowl stands upright the upper end 18 of the duct 14: is above the water level, whereas the lower end 19 of said duct stands adjacent the outlet 3 from the tobacco receptacle R to the chamber 4, or to the bore of the stem ifsaid chamber 4: should be reduced to such size that it is practically non-exist-- ent. By this I'mean to say that, while I have spoken of and shown the nicotin chamber as a chamber is only necessary to vthe extent that it forms a communication between the outlet 3, the lower end 19 of the duct, and the bore 2 of the stem; and therefore the use of the plugged opening in the chamber is more for the purpose of manufacture than otherwise, excepting when the chamber is of sufiicient size to permit the accumulation of nicotin as suggested above. In the normal position of parts with the water level below the upper end 18 of the duct, when the receptacle is filled with; tobacco and the same is lighted, the heat therefrom is communicated through the rather thin inner wall 12 to the water in the jacket 10, and the latter is in turn heated to such an extent that it throws ofi' steam or vapor. This rises into and accumulates within the upper portion of the jacket, and finally finds its escape through the duct 14 to the point 19, and therein mingles with the smoke drawn by the user through the outlet .3, so that combined smoke and vapor passes through the bore 2 of the stem and into his mouth. The result is found to be very pleasing and very satisfactory, and I hardly need enumerate the benefits which flow from this admixture of vapor with the smoke, especially as I reserve the privilege of using a variety of decided element of the structure, the.

inseam liquids in place of the element herein termed water. I have said that the type of pipe shown in 'Fig. 1 ''usually stands upright. Sometimes, however, the smoker permits the stem to hang from his mouth so that the smoker permits the stem to hang from his lips. But this form of pipe may be tilted the other way, or inward, and in case it is tilted to such an extent that the line Z designates a horizontal, then the liquid within the jacket will flow into the enlargement 20 and the water level would be approximately on the dotted line Z and yet none would flow out the duct. In either case we must remember that the jacket passes completely around the far side and the near side of the jacket, whereof in the views we see'only the outer and inner sides because the bowl is in section. The enlargement 20 may therefore be said to be adapted especially to pipes that are possible of being tipped or inclined toward the smoker, and that would hardly ever occur with the type of pipe shown in Fig. 1.

Referring now to Fig. 3, where my invention is shown as applied to a smoking tube T whose receptacle It may contain loose tobacco or the butt of a cigar in case this is a cigar holder, the numeral 3" designates the outlet for smoke from the receptacle, whence the smoke flows along the bore 2" and through the mouthpiece M, much as above. The numeral 10 designates the jacket which here surrounds the receptacle and is continued throughout the length of the tube for a considerable distance, and 16" designates the plug closing the filling orifice. The numeral 14: designates the duct or steam outlet whichin this case extends 'directly through the thin inner wall of the jacket at the point where the outlet 3 communicates with the bore 2". Here again it is intended to fill the jacket 10 a little less than half full, and the liquid therein would rise to about the dotted line. When the tube is held horizontal as shown no liquid will escape, when it is tilted upward the liquid will fiow'back toward the inner end of the tube and again no liquid will escape, and if it should be tilted downward (which is quite unlikely) the liquid in the jacket will flow into that portion thereof which surrounds the receptacle R. If the duct 14 is midway of the volume of the jacket and the liquid initially is less than half that volume, whichever end the tube is stood upon and whatever its oblique position, no water will flow out the duct. When the heat of the to- I The water being heated 1s converted into bacco burning within the receptacle becomes sufiicient to warm the inner wall of the jacket and through it the water within the same, steam will be generated and this will flow out the duct and mingle with the smoke drawn through the outlet 3", so.that the same results are produced.

These are but typical illustrations of the application of my idea to a smoking pipe or a smoking tube. It is possible that if the latter were used as a cigar holder, the heat of the burning tip would not be sufiicient to generate steam in the jacket because the fire is not contained within the receptacle; but at least the water in the jacket would be warmed and to an extent vaporized, and the vapor would mix with the smoke. I have said that I reserve the privilege of using other liquids than water. The liquid employed may be such that even a gentle heat will cause it to throw ofi' vapor, or it may have a certain aroma or some medical property or chemical afiinity for smoke, any and all of which will be enhanced by heat. The invention has for its fundamental principle the use of this heat which is always prevalent in a device of this kind, in its effect on the liquid within a surrounding jacket, and the-use of a acket around the hot bowl for tempering the heat of the latter.

The smoking pipe shown in Fig. 4 is one having a dropped stem S with the axis of its bowl alined withthe lower end of the stem, and here again the line X-X designates a horizontal and it will be observed that the tobacco receptacle R inclines toward its mouth and the tobacco would fall out if it were not for a closure in the shape of a lid 20 which may be hinged at 21 or otherwise held in place. The stem has a bore 22, the receptacle has an outlet 23, and between these elements is a nicotin chamber 24. Into the latter projects a nipple 25 which surrounds and continues the bore, and the stem may be connected with the shell of the nicotin chamber by means of screw threads 26 so that it can be unscrewed therefrom and withdrawn with its nipple for purposes of cleaning the chamber. The water jacket here again surrounds the bowl or receptacle R, but is formed eccentric thereto. That is to say, the water space 30 at the bottom is considerably smaller than the steam space 31 at the top, and from the latter a duct in the shape of a fine pipe 32 leads obliquely downward and constitutes a nipple 35 standing within the nicotin chamber 24, just above the outlet opening 23. Another nipple 34 opens obliquely upward from the water space 30 into this chamber just beneath the outlet 23. The water may be supplied through an opening into the steam space 31, closed by a plug 36 or other closure. substantially the same as above described.

steam which rises into the space 31, and flows thence through the duct 32 and is mixed with the smoke drawn into the mouth, the smoke passing through the ni pic 25 and the bore 22 of the stem. But is construction traps the nicotin within the champractically. stood on the mouthpiece M of the stem, the water in the space 30 might run out the nipple 34 into the nicotin chamber, but this is sometimes desirable as when it is intended to fiushthis chamber with the hot water in such. space: however this position of the pipe is abnormal and one which it will rarely if ever assume.

What is claimed as new is:-

1. The herein described smoking device comprising a tobacco receptacle surrounded by double walls producing between them a water jacket, the base of the device having a smoke outlet communicating with the receptacle and the jacket having a duct connecting with said smoke outlet.

2. The herein described smoking pipe comprising a bowl whose tobacco receptacle is surrounded by double walls producing The action is.

between them a water jacket, the base of I the bowl having a chamber communicating with the receptacle through a smoke outlet at the lower end of such receptacle, the inner wall also having a duct connecting the upper portion of the jacket with the upper portion of the chamber, the latter having a nicotin opening in its bottom, a plug for closing the same, and a stem leading from the nicotin chamber.

3. The herein described smoking pipe having the upper portion of its tobacco receptacle surrounded by a water jacket and jacket is substantially half full, and a stem opening from said chamber.

4. The herein described smoking pipe whose bowl is surrounded by a water jacket enlarged at the inner side of the bowl, the lower end of the latter having a nicotin chamber and the upper part a tobacco receptacle connected therewith by a smoke outlet and connected with the upper portion of the inner side of said jacket by a duct opening into the chamber adjacent said out- 1et,va stem communicating with said cham her and standing oblique to the normally vertical axis of said bowl, and a filling opening in the outer Wall of the jacket at a point between the enlargement and stem.

In testimony whereof I afiix my signature.
